INNER SOLE.

SPECIFICATION forming part of Letters Patent No. 240,392, dated April 19, 1881.

Application filed March 24, 1879.

\ of Massachusetts, have invented certain new and useful Improvements in Inner Soles, of which the following is a specification.

This invention relates to that class of boots and shoes in which the lines of stitching and of clinching tack-points which secure the sole to upper are covered by a portion of the inner sole, so as to protect the foot of the wearer from such linesof stitching and clinched tackpoints.

Prior to my invention it has been proposed to make a cut in the inner sole and turn back the lip formed thereby, and then to stitch the shoe, so that after such stitching the lip may be turned down upon the stitches. It has also been proposed to secure a thin veneer to the inner sole, and after the tacking and stitching to cement such veneer down upon the inner sole, so as to cover the stitches and clinched tack ends.

My improvement consists in an inner sole having one side or face channeled, as it is termed-that is, slit parallel, or nearly so, to such face from a point at or near its edge and for a short distance therefrom-which produces a lip that is prepared with an india-rubber or other suitable cement, so that after such inner sole has been stitched or otherwise fastened to the upper and the outer sole of a boot or shoe the said lip can be secured over the exposed portions of such fastening devices, cou-' cealing and covering the same from view, the above preparation of the sole being all previous to its attachment to the upper preparatory to being fastened thereto and to the outer sole.

In the accompanying drawings, Figure 1 is a plan view of my improved inner sole; Fig. 2, a cross-section on line mm, Fig. 1. Fig. 3 is a similar view, showing the sole with the lip cut from the edge.

In the drawings, A indicates an inner sole of any of the usual shapes and sizes; B, the

inner face or side of the sole, at which, parallel or nearly so thereto from the edge a of the sole, the leather is slit, making a lip, b, which is coated with cement on its inner surface, 0.

This, in substance, constitutes my improved inner sole, and such preparation of the same is all previous to the lasting.process, as and for the purpose described.

' sole being formed integral with the lip enables the inner sole, after the sole is stitched or nailed to the shoe, to be secured in position, and in the present invention the cementing of the lip of the channeled inner sole previous to its being applied to the shoe obviously pre sents many advantages over the ways just described, inasmuch as it can be done much easier and quicker, necessarily saving expense in the manufacture, and it will be neater and in every way better, and after the boot or shoe is lasted and outer sole applied either by stitches or nails, &c., the lip can be easily, readily, or firmly secured to the sole, and when thus secured a clean and neat appearance is presented by the surfaces of the upper and inner sole in the inside of the boot or shoe.

Having thus described my invention, what I claim is- An inner sole for boots and shoes, formed with a channel, d, and a lip, I), made integral with the sole, and turned back from said channel and coated with cement, substantially as described.
